BJ8 Rear Brake Questions/Advice

Gentleman-

I am having an issue with my rear brakes- or at least I think I am. Recently, after driving as little as 15-20 miles, I notice a strong smell from both rear wheels, and is sure smells like brake pad/shoe to me. The wheels are also warm, or seem warm to me. After a 15 mile ride, my laser tem gun shows the drums anywhere from 135-155F degrees. The car seems to roll easily when in neutral, so I don’t think anything is hanging up.

I took apart both rear brakes over the weekend. Everything looks fine, and I made some adjustments so the drum turned easily and free when in neutral. It seemed a little tight before I made these adjustments. The shoes have plenty of material on them, and when you smell the shoe, it’s the same small I experience after driving.

Thought I was in good shape, but an easy 30 minute drive and the smell and heat was back.

My question- the pads/shoes are old, but don’t have that many miles on them. I would guess they are at least 10 years old, maybe more. Do the shoes go bad over time, or maybe they got really hot and they are just out of life, even though the material thickness is adequate?

I never noticed the heat before the smell showed up- is 135-15F5 degrees measured on the drum itself high?

I am hopeful the answer is just a new set of pads/shoes, but figured I would ask for some advice here before I go and throw new parts at the problem.

Other notes- no known leaks in the brake system. Brake fluid level is constant in the reservoir. Car stops well. Hand brake functions, and the brake servo was replaced several years ago, and has about 2000 miles on it. Car rolls easily when pressing in the clutch before applying the brakes.

I appreciate any advice!

I would check the wheel cylinders maybe their getting stuck try bleeding them before you tear the whole thing down
 
Check the linings as to position, since one lining can be installed either way. Opening for parking brake lever should be 180 degrees from the other opening. Good time to check springs and adjusters for free movement.

although not as bad as yours, my rear brakes hanging up a bit was the rubber hose just before T near the differential. Seems it swells from the inside so pressure on application forces fluid through, but very very slowly allows the pressure to "bleed" out. I had replaced or rebuilt everything at rear until someone on board mentioned the rubber hose, kinda out of sight if just lifting rear a bit so out of sight out mind.
 
I'm going to say is pretty obvious, but the only time that has happened to me that was because my Handbrake had not dropped completely and not I realized. It is not visually noticeable but one or two teeth by lower were missing and rear lugs brushed continuously.
